On Sunday, Devin P. Kelley, 26, arrived at First Baptist Church dressed in black, wearing a tactical vest and carrying an AR-15-style assault rifle and opened fire in and outside the church.

In all, Kelley killed 26 people and injured 20 more. As he was exiting the church, a neighbor opened fire on him, causing him to drop his weapon and flee in his vehicle. The neighbor and another bystander followed him in a truck until Kelley drove off the road, mortally wounded.

Victims of Kelley ranged in age from 5 to 72 years old.

The shooting was the fifth deadliest in American history and the deadliest in Texas' history.
